TM 55-1510-221-10CHAPTER 9EMERGENCY PROCEDURESSection I. AIRCRAFT SYSTEMS9-1. AIRCRAFT SYSTEMS.9-4. AFTER EMERGENCY ACTION.This section describes the aircraft systems emer-gencies that may reasonably be expected to occurand presents the procedures to be followed. Emer-gency procedures are given in checklist form whenapplicable. A condensed version of these proceduresis in the Operators and Crewmembers Checklist,TM 55-1510-221-CL. Emergency operations of avi-onics equipment are covered when appropriate inChapter 3, Avionics, and are repeated in this sectiononly as safety of flight is affected.After a malfunction has occurred, appropriateemergency actions have been taken, and the aircraftis on the ground, an entry shall be made in theremarks section of DA Form 2408-13 describing themalfunction.9-5. EMERGENCY EXITS AND EQUIPMENT.Emergency exits and equipment are shown infigure 9-1.9-6. EMERGENCY ENTRANCE.9-2. IMMEDIATEACTIONEMERGENCYCHECKS.Immediate action emergency items are under-lined for your reference and shall be committed tomemory. During an emergency, the checklist will becalled for to verify the memory steps performed andto assist in completing any additional emergencyprocedures.Entry may be made through the cabin emer-gency hatch. The hatch may be released by pullingon its flush-mounted pull-out handle, placardedEMERGENCY EXIT - PULL HANDLE TORELEASE. The hatch is of the nonhinged plug typewhich removes completely from the frame when thelatches are released. After the latches are released,the hatch may be pushed in.NOTE9-7. ENGINE MALFUNCTION.The urgency of certain emergenciesrequires immediate action by the pilot.The most important single considerationis aircraft control. All procedures are sub-ordinate to this requirement. Reset MAS-TER CAUTION after each malfunctionto allow systems to respond to subsequentmalfunctions.9-3. DEFINITION OF LANDING TERMS.The term LANDING IMMEDIATELY isdefined as executing a landing without delay. (Theprimary consideration is to assure the survival ofoccupants.) The term LAND AS SOON AS POSSI-BLE is defined as executing a landing at the nearestsuitable landing area without delay. The termLAND AS SOON AS PRACTICABLE is defined asexecuting a landing to the nearest suitable airfield.a.Flight Characteristics Under Partial PowerConditions. There are no unusual flight characteris-tics during single-engine operation as long as air-speed is maintained at or above minimum controlspeed (V,,) and above power-off stall speed. Thecapability of the aircraft to climb or maintain levelflight depends on configuration, gross weight, alti-tude, and outside air temperature. Performance andcontrol will improve by feathering the propeller ofthe inoperative engine, retracting the landing gearand flaps, and establishing the appropriate single-engine best rate-of-climb speed (V yse). Minimumcontrol speed (V,,) with flaps retracted is approxi-mately 1 knot higher than with flaps at takeoff (40%)position.b. Engine Malfunction During And AfterTakeoff. The action to be taken in the event of anengine malfunction during takeoff depends onwhether or not liftoff speed (V 1of) has been attained.If an engine fails immediately after liftoff, manyvariables such as airspeed, runway remaining, air-9-1
